The Item below amends and supplements the information disclosed under the corresponding Item of the Schedule 13D. Except as specifically provided herein, this Amendment No. 11 does not modify any of the information previously reported in the Schedule 13D.

(ii)

True Wind Capital, L.P., a Delaware limited partnership (“True Wind Capital” and, together with Zephyr Holdco, “True Wind”),

(iii)

True Wind Capital GP, LLC, a Delaware limited liability company (“True Wind Capital GP”),

Item 4.

Purpose of the Transaction.

Item 4 of the Schedule 13D is hereby amended and supplemented as follows:

The information set forth in Item 6 to this Amendment is incorporated by reference in its entirety into this Item 4.

Item 5.

Interest in Securities of the Issuer.

Item 5 of the Schedule 13D is hereby amended and restated as follows:

The information contained in rows 7, 8, 9, 10, 11 and 13 on each of the cover pages of the Schedule 13D and the information set forth or incorporated in Items 2, 3 and 6 of the Schedule 13D is hereby incorporated by reference in its entirety into this Item 5.

(a) – (b)

Zephyr Holdco holds 100,206 shares of Series A Preferred Stock as of the date hereof. Series A Preferred Stock initially has a Stated Value of $1,000 per share, which accretes at a fixed rate of 8.0% per annum, compounded quarterly (the “Accreted Value”). Each share of Series A Preferred Stock is convertible into (i) the number of shares of Common Stock equal to the product of (A) the Accreted Value with respect to such share on the conversion date multiplied by (B) the Conversion Rate as of the applicable conversion date divided by (C) 1,000 plus (ii) cash in lieu of fractional shares. As a result of this accretion, the number of shares of Common Stock into which each share of Series A Preferred Stock may be converted will increase over time. The Conversion Rate is currently equal to 166.11 shares. The conversion rate is subject to adjustment from time to time upon the occurrence of certain customary events in accordance with the terms of the Series A Certificate of Designations. As of November 7, 2021, the 100,206 shares of Series A Preferred Stock are convertible into 20,645,233 shares of Common Stock.

All of the computations and share amounts used herein do not give effect to any future accretion on the shares of Preferred Stock. As a result of its beneficial ownership of Series A Preferred Stock, as described above, the Reporting Persons may be deemed to beneficially own an aggregate of 20,645,233 shares of Common Stock of the Issuer, which would be received upon conversion of the Series A Preferred Stock, representing in the aggregate approximately 26.7% of the issued and outstanding shares of Common Stock of the Issuer as calculated pursuant to Rule 13d-3 of the Securities Exchange Act of 1934.

The percentages of beneficial ownership in this Schedule 13D are based on (i) an assumed conversion by the Reporting Persons of 100,206 shares of Series A Preferred Stock into 20,645,233 shares of Common Stock, as of the date hereof and (ii) 56,790,468 shares of Common Stock outstanding as of November 5, 2021, as represented by the Issuer in the Merger Agreement (as defined below).

The information set forth in Item 6 to this Amendment is incorporated by reference in its entirety into this Item 5.

Item 6.

Contracts, Arrangements, Understandings or Relationships With Respect to Securities of the Issuer.

Item 6 of the Schedule 13D is hereby amended and supplemented as follows:

Merger Agreement

On November 7, 2021, the Issuer entered into an Agreement and Plan of Merger with Open Text Corporation, a Canadian corporation (“Parent” and such agreement, the “Merger Agreement”), pursuant to which, among other things and subject to the terms and conditions set forth therein, (1) a wholly-owned subsidiary of Parent to be formed (“Merger Sub”) will commence a cash tender offer no later than November 19, 2021 to acquire all of the outstanding shares of Common Stock at an offer price per share of $8.50, without interest and subject to any applicable withholding taxes (the “Offer Price” and such offer, the “Offer”), net to the seller in cash and (2) as promptly as practicable following the consummation of the Offer, upon the terms and subject to the conditions set forth in the Merger Agreement, Parent will merge with and into the Issuer, with the Issuer surviving as a wholly owned subsidiary of the Parent (the “Merger”), without a meeting of stockholders of the Issuer. The Merger Agreement provides that, at the effective time of the Merger and subject to the terms thereof, (i) each share of common stock, par value $0.0001 per share, of Merger Sub that is outstanding as of immediately prior to the effective time, will be converted into one validly issued, fully paid and nonassessable share of common stock of the Issuer; (ii) each share of Common Stock that is (a) held by the Company as treasury stock; (b) owned by Parent or Merger Sub; or (c) owned by any subsidiary of the Company, Parent or Merger Sub as of immediately prior to the effective time will be cancelled and extinguished without any conversion thereof or consideration paid thereof; and (iii) each share of Common Stock that is issued and outstanding as of immediately prior to the effective time (other than those described in clauses (ii) and (iii) above) will be cancelled and extinguished and automatically converted into the right to receive the Offer Price.

The Merger Agreement provides that Merger Sub’s obligation to pay for any shares of Common Stock tendered pursuant to the Offer is subject to certain conditions, including that at least one share of Common Stock more than two-thirds of the sum of (i) all shares of Common Stock issued and outstanding and (ii) the largest number of shares of Common Stock into which shares of Series A Preferred Stock are convertible, in each case calculated at the expiration of the Offer must be tendered prior to the expiration of the Offer (such condition, the “Minimum Condition”).

Support Agreement

On November 7, 2021, concurrently with the execution of the Merger Agreement, Zephyr Holdco entered into a Tender and Voting Agreement with Parent and the Issuer (the “Tender and Voting Agreement”). Pursuant to the Tender and Voting Agreement, Zephyr Holdco agreed, among other things, (i) to convert, immediately prior to the expiration of the Offer, each share of Series A Preferred Stock into shares of Common Stock (the “Subject Shares”), subject to certain exceptions; (ii) to tender such Subject Shares pursuant to the Offer and not withdraw such tender, subject to certain exceptions; (iii) vote the Subject Shares against (a) any Acquisition Proposal (as defined in the Merger Agreement), (b) any merger (other than the Merger), consolidation or other combination involving the Issuer or the Issuer’s subsidiaries or a reorganization, recapitalization, extraordinary dividend, dissolution or liquidation of the Issuer or any of its subsidiaries, (c) to the extent submitted to a stockholder vote, any change in the business, management or board of directors of the Issuer (other than as directed by Parent or Merger Sub) or (d) any other action, proposal or agreement that would (1) reasonably be expected, to impede, interfere with, materially delay or postpone the Merger or the other transactions contemplated by the Merger Agreement, (2) result in any of the conditions to the Offer or conditions to the Merger not being fulfilled or satisfied or (3) change in any manner the dividend policy or capitalization of, including the voting rights of any class of equity interests in, the Company. The Tender and Voting Agreement terminates in the event that the Merger Agreement is terminated.

The conversion of Zephyr Holdco’s shares of Series A Preferred Stock into Common Stock and tender of Subject Shares by Zephyr Holdco is subject to certain conditions, including that (i) all conditions (other than the Minimum Condition) to the Offer in the Merger Agreement are satisfied and (ii) upon conversion by Zephyr Holdco of its Series A Preferred Stock into Common Stock and the tender of such Subject Shares, the Minimum Condition will have been satisfied.

The foregoing summaries of the Merger Agreement and the Tender and Voting Agreement are not intended to be complete and are qualified in their entirety by reference to the full text of such documents, which are filed as exhibits to this Schedule 13D and are incorporated herein by reference.
